Three-phase system insulation monitor ISOMETER® iso685-…-B series

medium-voltagefor AC networksAC/DC

Predefined measurement profiles Reliable measurement of insulation resistance, voltage, capacitance and frequency Integrated web server Modbus TCP/RTU Can be used in coupled IT systems The ISOMETER® is an insulation monitoring devices in accordance with IEC 61557-8 for IT systems. The devices are universally applicable in AC, 3(N)AC, AC/DC and DC systems. AC systems may include extensive DC-supplied loads (such as rectifiers, inverters, variable-speed drives). Device variants iso685-D: This device variant ISOMETER® iso685-D features a high-resolution graphic LC display and operating controls for direct operation of the device functions. It cannot be combined with an FP200. iso685-S: This device variant ISOMETER® iso685-S features neither a display nor operating controls. It can only be used in combination with the FP200 and it is operated via this front panel. Option "W": The ISOMETER®s with and without integrated display are available with option „W“ for extreme climatic and mechanical conditions (ISOMETER® iso685W-D and iso685W-S). Features ISOMETER® for IT AC systems with galvanically connected rectifiers or inverters and for IT DC systems (IT = unearthed systems) Automatic adaptation to the existing system leakage capacitance Combination of AMPPlus and other profilespecific measurement methods Two separately adjustable response value ranges of 1 kΩ…10 MΩ High-resolution graphic LC display for excellent readability and recording of the device status Connection monitoring (monitoring of the measuring lines) Automatic device self test Graphical representation of the insulation resistance over time (isoGraph)
